Inspector Montalbano (1999)

S6E2 The Game of Three Cards

The passing of prominent builder Girolamo Cascio prompts Montalbano to revisit the unsolved murder of Cascio's main rival, Giacomo Aletto, who was gunned down twenty years ago. Aletto's associate, Rocco Pennisi, was imprisoned for the murder, but Montalbano begins to question whether justice was truly served.
